Some interesting comments by Roger Sperberg on the OpenReader format:

http://www.teleread.org/blog/?p=4473 asks whether OpenReader should
"consider OpenDocument's goals and principles", and includes a long
discussion by various interested parties. It also includes a pointer
to Sophie, "an open-source platform for creating and reading
electronic books for the networked environment"
(http://www.futureofthebook.org/blog/archives/2006/03/sophie_is_coming_1.html)

Hmmm. Isn't that Nvu (http://www.nvu.com/)?

http://www.teleread.org/blog/?p=4509, entited "What's the Point of
OpenReader?", makes some points about goals which perhaps should be
included for the OpenReader format, such as a purely textual
single-file format.

(Oddly enough, these both appear on David Rothman's blog, rather than
appearing on the openreader-format mailing list ostensibly set up to
discuss this issue. You'd think that David, being an OR principal,
would encourage Roger to either post to this mailing list in the first
place, or to at least post pointers to this mailing list. Perhaps in
the future... :-)
